1. Strategy

Strategy, a prominent business analytics platform turned Bitcoin treasury company, has adopted BTC as its primary reserve asset. The company is perhaps better known as MicroStrategy, but changed its name in February 2025 with co-founder Michael Saylor citing the “power and positivity” of “strategy.” 

The firm, which produces mobile software and provides cloud-based services, has aggressively pursued a Bitcoin buying spree, scooping up millions of dollars worth of the cryptocurrency. As of this writing, it holds 780,897 BTC in reserve, equivalent to $59 billion and more than 3.7% of the total amount of Bitcoin that will ever be issued.
